    Initialise DNS TTL for A and AAAA records.
    
    So far, the TTLs for both A and AAAA records were not initialised,
    resulting in exit relays sending back the value 60 to Tor clients.  This
    also impacts exit relays' DNS cache -- the expiry time for all domains
    is set to 60.
    
    This fixes <https://bugs.torproject.org/19025>.
